"It depends". I'm fond of Spoiler Warning, which I've been watching for a while, because it's a bunch of 30-somethings (like me) doing interesting game criticism in addition to the other things Let's Plays usually do. They're actually one of the earlier iterations of the idea. I also don't get the appeal of watching someone simply play the game and just generally react, when I could be playing it (or something else) myself. I've only sampled those streams every so often just to check the game itself out (i.e., briefly just sampled about 3 minutes of Angry Joe's Fallout 4 stream, just to see completely unvarnished, real footage).

On the topic of 30-somethings, while you may hear a lot more about the youth, I gotta say there's a lot of "30 somethings" in the general "Internet video" space, doing various interesting works. I noticed once I started getting into Patreon that without particularly meaning to be hipster, an awful lot of my entertainment time is spent on grain-fed, organically-raised artisanal Internet video now. It just sorta... happened.
